      2002 and for the three month and six month periods ended June 30, 2002 and
      2001 is unaudited, but in the opinion of the management of DSET
      Corporation ("DSET" or the "Company"), contains all adjustments
      (consisting only of normal recurring adjustments) which the Company
      considers necessary for the fair presentation of the Company's financial
      position as of June 30, 2002, the results of its operations and its cash
      flows for the three and six month periods ended June 30, 2002 and 2001.
      The financial statements included herein have been prepared in accordance
      with generally accepted accounting principles and the instructions to Form
      10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information
      and footnote disclosures normally included in financial statements
      prepared in accordance with generally accepted accounting principles have
      been condensed or omitted. These financial statements should be read in
      conjunction with the Company's audited financial statements and
      accompanying notes and Management's Discussion and Analysis of Financial
      Condition and Results of Operations contained in the Company's Annual
      Report on Form 10-K for the year ended December 31, 2001 as amended. The
      December 31, 2001 balance sheet data contained in this Form 10-Q was
      derived from audited financial statements, but does not include all the
      disclosures required by generally accepted accounting principles.

      Results for the interim period are not necessarily indicative of results
      that may be expected for the entire year.

      On August 14, 2001 the Company announced a reverse stock split effective
      on the close of business on August 21, 2001, pursuant to which one new
      share of common stock of the Company was issued in exchange for each four
      outstanding shares of common stock. The Board of Directors approved the
      reverse split under New Jersey law and also authorized the reduction of
      the Company's authorized common stock four-fold from 40,000,000 to
      10,000,000 shares. The Company's common stock commenced trading at the
      post-split price on August 22, 2001. All share and per share amounts in
      this Form 10-Q have been adjusted retroactively to reflect the
      one-for-four reverse stock split.

      Effective with the May 2002 restructuring (see Note 6) , DSET's corporate
      headquarters changed from Bridgewater, New Jersey to Shrewsbury, New
      Jersey and Mr. Binay Sugla replaced Mr. William McHale as Chief Executive
      Officer. Mr. McHale separated from the Company effective May 24, 2002 but
      remains on the Board of Directors.

2.    Going Concern

      The condensed consolidated financial statements of DSET have been prepared
      on the basis that DSET will continue as a going concern, which
      contemplates the realization of assets and satisfaction of liabilities and
      commitments in the normal course of business. At June 30, 2002 and

Notes to Condensed Consolidated Financial Statements (Unaudited)


      December 31, 2001, DSET had an accumulated deficit of $52.4 million and
      $35.8 million and working capital (deficit) of ($200,000) and $8.5
      million, respectively. DSET also incurred net losses of $14.8 million and
      $16.6 million for the three and six month periods ended June 30, 2002,
      respectively, and $33.3 million for the year ended December 31, 2001.
      These factors raise substantial doubt about DSET's ability to continue as
      a going concern. The losses and deficits resulted principally from the
      lack of demand for DSET's products due to a major downturn in the
      telecommunications industry which began in the second half of 2000 (and
      continues to the present), having its most acute impact on Competitive
      Service Providers ("CSPs"), the Company's primary targeted customers. This
      downturn was brought about by the sudden withdrawal of available financing
      to the CSPs from traditional sources. Many of the Company's customers have
      declared bankruptcy, refused to pay or delayed additional purchases. This
      has resulted in the impairment of tangible and intangible assets, excess
      capacities and substantial bad debts. The Company has taken action to
      mitigate these circumstances by reducing headcount, subletting facilities
      and searching for additional financing to enable it to fund its return to
      positive cash flow and profitability.

      In 2002 DSET received three non-compliance notifications from the Nasdaq
      Stock Market, Inc. ("Nasdaq").

      On February 14, 2002, the Company received notice from Nasdaq that for the
      preceding 30 consecutive trading days, the Company's common stock had not
      maintained the minimum Market Value of Publicly Held Shares ("MVPHS") of
      $5,000,000 as required for continued inclusion by Marketplace Rule
      4450(a)(2) on the Nasdaq National Market. MVPHS equals the closing bid
      price multiplied by that portion of a company's outstanding shares which
      is in the hands of public investors (i.e., - shares not held by company
      officers, directors, or investors who hold a controlling interest in the
      company.) Therefore, in accordance with Marketplace Rule 4450(e)(1), the
      Company had 90 calendar days, or until May 15, 2002, to regain compliance.

      On March 5, 2002, the Company received notice from Nasdaq that for the
      previous 30 consecutive trading days, the price of the Company's common
      stock had closed below the minimum $1.00 per share requirement for
      continued inclusion under Marketplace Rule 4450(a)(5). Therefore, in
      accordance with Marketplace Rule 4450(e)(2), the Company had 90 calendar
      days, or until June 3, 2002, to regain compliance. If compliance with this
      rule could not be demonstrated by June 3, 2002, the Company's securities
      would have been delisted from the Nasdaq National Market.

      Effective May 29, 2002 the Company transferred the trading of its common
      stock to the Nasdaq SmallCap Market.

      On July 17, 2002, the Company received notice from Nasdaq that for the
      previous 30 consecutive trading days, the price of the Company's common
      stock had not maintained a minimum market value of publicly held shares of
      $1,000,000 as required for continued inclusion by Marketplace Rule
      4310(c)(7). Therefore, in accordance with Marketplace Rule 4310(c)(8)(B),
      the Company has 90 calendar days, or until October 15, 2002, to regain
      compliance. If compliance with the $1,000,000 rule cannot be demonstrated
      by October 15, 2002, the Company's securities will receive a written
      notification from Nasdaq that the Company's securities will be delisted.

      DSET's failure to meet the Nasdaq's maintenance criteria in the future may
      result in the delisting of its common stock from the Nasdaq SmallCap
      Market. In such event, trading, if any, of DSET's common stock may then
      continue to be conducted in the over-the-counter market, on the
      over-the-counter bulletin board or other electronic quotation services. As
      a result, an investor may find it more difficult to dispose of or obtain
      accurate quotations as to the market value of DSET's common stock. In
      addition, in the event DSET's common stock is delisted, broker-dealers
      would have certain regulatory burdens imposed upon them, which may
      discourage them from effecting transactions in DSET's common stock,
      further limiting the liquidity thereof. This may have the effect of
      limiting DSET's ability to raise additional financing.

      DSET's ability to continue as a going concern is dependent upon its
      ability to generate sufficient cash flows to meet its obligations as they
      come due. DSET believes that the cost reductions from its restructurings
      in 2001 and 2002 (including work force reductions) and the merger with
      ISPsoft will enhance its cash flows from operations. The Company is
      seeking additional financing to fund its operating and capital
      requirements through 2002. If cash flows are insufficient or the Company
      is unable to raise funds on acceptable terms, there would be a material
      adverse effect on DSET's financial position and operations and its ability
      to continue as a going concern. This would force DSET to further reduce
      its capital expenditures, reduce its workforce, sell certain assets or
      possibly explore additional alternatives including seeking bankruptcy
      protection. The consolidated financial statements do not include any
      adjustments relating to the recoverability of the carrying amount of the
      recorded assets or the amount of liabilities that might result from the
      outcome of these uncertainties. The Company cannot be certain that
      additional debt or equity financing will be available when required or, if
      available, that it can secure it on terms satisfactory to the Company.

3.    Summary of Significant Accounting Policies

      The condensed consolidated financial statements include all wholly-owned
      subsidiaries from the respective dates of their acquisition or formation.
      The consolidated entity includes DSET Corporation and its wholly-owned

      and DSET Canada, Inc. ("Canada"). All significant intercompany
      transactions have been eliminated in consolidation.

      Goodwill
      Goodwill represents the excess of the purchase price of an acquistion over
      the fair value of the net tangible and intangible assets acquired. In
      accordance with Statement of Financial Accounting Standards ("SFAS") 142
      "Goodwill and Other Intangible Assets", the Company ceased amortizing
      goodwill effective January 1, 2002. In 2001 the Company amortized goodwill
      using a straight-line method over an estimated useful life of five years.
      The Company periodically tests goodwill for impairment by comparing its
      carrying amount to the fair value of goodwill. Accumulated amortization
      was zero and $162,000 as of June 30, 2002 and December 31, 2001,
      respectively. On January 31, 2002 the Company merged with ISPsoft Inc. In
      accordance with SFAS 141, "Business Combinations", the merger was
      accounted for a purchase resulting in the recording of approximately $11.4
      million in goodwill.

      In the second quarter of 2002, the Company recognized a $11.4 million
      write-down of goodwill due to the significant decline in the valuation of
      the Company's stock due to the negative industry and economic trends
      affecting both the Company's current operations and expected future sales
      as well as the general decline of technology valuations. In accordance
      with SFAS 142, the Company performed an assessment of the carrying value
      of its goodwill and other intangible assets recorded in connection with
      the Company's various acquisitions. The fair value of goodwill was
      determined based on the market value of the Company (see Note 8).

      Acquired Technology
      Acquired technology represents the costs of feasible technology acquired
      from external sources. Amortization of acquired technology is the greater
      of the amount computed using (a) the ratio that current gross revenues for
      a product bears to the total of current and anticipated future gross
      revenues for that product or (b) the straight-line method over the
      remaining estimated economic life ranging from three to five years of the
      product including the period being reported on. The acquired technology,
      resulting from the Company's merger with ISPsoft Inc., was valued at $4.0
      million. It was determined that the technology had a finite life of five
      years from the time of purchase. In the second quarter of 2002,
      amortization expense of $200,000 was recognized as cost of revenues. In
      the six months ended June 30, 2002, amortization expense of $333,333 was
      recognized as cost of revenues. Based upon managements current plans, the
      remaining balance of acquired technology is expected to be recovered from
      the sale of related products (see Note 7).

      Research and Product Development
      Research and product development costs are charged to expense as incurred.
      However, the costs incurred for the development of computer software that
      will be sold, leased, or otherwise marketed are capitalized when
      technological feasibility has been established.

      Long-Lived Assets
      In August 2001, SFAS 144, "Accounting for the Impairment or Disposal of
      Long-Lived Assets", was issued, replacing SFAS 121, "Accounting for the
      Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
      Of" and portions of APB Opinion 30, "Reporting the Results of Operations".
      SFAS 144 provides a single accounting model for long-lived assets to be
      disposed of and changes the criteria to be met to classify an asset as
      held-for-sale. SFAS 144 retains the requirement of APB Opinion 30 to
      report discontinued operations separately from continuing operations and
      extends that reporting to a component of an entity that either has been
      disposed of or is classified as held-for-sale. The Company adopted SFAS
      144 effective January 1, 2002 and there was no impact on the condensed
      consolidated financial statements at adoption.

      Treasury Stock
      The Company's purchases of shares of its common stock are recorded, at
      cost, as Treasury Stock and results in a reduction of stockholders'
      equity. When treasury shares are reissued, the Company uses a first-in,
      first-out method and the difference between the repurchase cost and the
      reissuance price is treated as an adjustment to common stock.

      Revenue Recognition
      License revenues are comprised of one time license fees for software
      products released for general availability, royalties from third party
      licensees, and repetitive license royalty fees for applications that are
      sold on a multiple use basis. Revenue for the one time license fees is
      recognized when there is persuasive evidence that an arrangement exists,
      delivery has occurred, the fee is fixed and determinable and collection is
      probable. Royalty revenue for the multiple use licenses is recognized when
      the customer sells a product within which is embedded libraries of the
      application development tools. The contracts for multiple-use licenses do
      not call for any minimum royalties.

      Service revenues are comprised of postcontract customer support service
      fees, gateway rental fees, professional service fees which include
      training, consulting, installation, implementation, and charges for
      reimbursable expenses and custom product development fees. Revenues for
      postcontract customer support services and gateway rental fees are
      recognized ratably over the period in which the services are provided.
      Revenues for training in the Company's products are recognized when the
      training has been completed. Revenues for consulting services are
      recognized in the period in which the consulting services are provided.
      Revenues for product installation and implementation services are
      recognized when contractually agreed upon milestones have been achieved.
      It is not necessary for the Company to provide implementation services.
      Outside third parties are available to perform integration of the
      Company's software with the customer's systems or the customer can choose
      to install the software. Revenues for reimbursable expenses are recognized
      as the expenses are incurred. Revenues for custom product development are
      recognized under the contract method of accounting in accordance with
      AICPA Statement of Position 81-1,

      "Accounting for Performance of Construction-Type and Certain
      Production-Type Contracts" since they generally require significant
      production, modification or customization of the Company's products.
      Revenue for custom product development is recognized as a percentage of
      the contract completed based upon the ratio of direct labor costs incurred
      to the estimated total direct labor costs required for the project. Any
      revenue for custom product development that is recognized in excess of
      amounts invoiced to the customer for progress billings is recorded as
      unbilled accounts receivable.

      Some customer contracts provide for multiple elements to be delivered (for
      example, electronic-bonding gateway product, postcontract customer
      support, training, custom product development, etc.). In those contracts
      that include multiple elements, the contract fee is allocated to the
      various elements based on vendor-specific objective evidence ("VSOE") of
      fair value. VSOE of fair value is the price charged when the same element
      is sold separately, or for an element not yet being sold separately, the
      price established by the Company's product management department.

      In 2001, the Company began a new gateway rental program which provides
      existing and prospective customers the ability to rent electronic-bonding
      gateways on a month-to-month basis, with a 90-day cancellation provision.
      The program includes the use of the software, technical support, software
      upgrades and change management services for a monthly fee. Revenue under
      this program is recognized pro rata as customers use the Company's
      software and services.

      Income Taxes
      The Company utilizes an asset and liability approach for financial
      reporting for income taxes. Deferred income tax assets and liabilities are
      computed for differences between the financial statement and tax bases of
      assets and liabilities that will result in taxable or deductible amounts
      in the future, based on enacted tax laws and rates applicable to the
      period in which the differences are expected to affect taxable income.
      Valuation allowances are established, when necessary, to reduce the
      deferred tax assets to the amount more likely than not to be realized.

      For certain stock options, the Company receives a tax deduction for the
      difference between the fair value at the date of exercise of the stock
      option and the exercise price. To the extent the amount deducted for
      income taxes exceeds the amount charged to operations for financial
      statement purposes, the related tax benefits are credited to shareholders'
      equity.

      The tax benefit of $1.4 million recorded in the first quarter of 2002
      related to the Job Creation and Worker Assistance Act ("JCWAA") signed
      into law in March 2002, which allows an extension to the general net
      operating loss carry-back period to five years (from two years). An
      additional tax benefit of $449,000 was recorded in the second quarter of
      2002 related to the research and development tax credit and the foreign
      tax credit released as a result of the carry-back related to the JCWAA.
      This benefit was recorded in the second quarter as a result of further
      clarification of this new legislation.

      Reclassifications
      Certain amounts in 2001 have been reclassified to conform to the current
      period presentation.

      New Accounting Standards
      In August 2001, the Financial Accounting Standards Board ("FASB") issued
      SFAS 143, "Accounting for Asset Retirement Obligations", which addresses
      financial accounting and reporting obligations associated with the
      retirement of tangible long-lived assets and the associated asset
      retirement costs. The Statement applies to legal obligations associated
      with the retirement of long-lived assets that result from the acquisition,
      construction, development, and (or) the normal operation of a long-lived
      asset, except for certain obligations of lessees. The effective date for
      SFAS 143 is for financial statements issued for fiscal years beginning
      after June 15, 2002. The Company does not expect that the adoption of the
      provisions of SFAS 143 will have a material impact on its results of
      operations or financial position.

      In April 2002, the FASB issued SFAS 145, "Rescission of FASB Statements
      No. 4, 44 and 64, Amendment to FASB Statement No. 13, and Technical
      Corrections". SFAS 145 eliminates the requirement (in SFAS No. 4) that
      gains and losses from the extinguishments of debt be aggregated and
      classified as extraordinary items, net of the related income tax. In
      addition, SFAS No. 145 requires sales-lease back treatment for certain
      modifications of a capital lease that result in the lease being classified
      as an operating lease. The rescission of SFAS No. 4 is effective for
      fiscal years beginning after May 15, 2002, which for the Company would be
      December 31, 2003. Earlier application is encouraged. Any gain or loss on
      extinguishment of debt that was previously classified as an extraordinary
      item would be reclassified to other income (expense). The remainder of the
      statement is generally effective for transactions occurring after May 15,
      2002. The Company does not expect that the adoption of SFAS No. 145 will
      have a material impact on the Company's financial condition, cash flows
      and results of operations.

      In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs
      Associated with Exit or Disposal Activities". SFAS 146 requires recording
      costs associated with exit or disposal activities at their fair values
      when a liability has been incurred. Under previous guidance, certain exit
      costs were accrued upon management's commitment to an exit plan, which is
      generally before an actual liability has been incurred. Adoption of SFAS
      146 is required with the beginning of fiscal year 2003.

4.    Revenue Concentration

      The Company had two customers accounting for 12% of revenues each for the
      quarter ended June 30, 2002 and two customers that accounted for 14% and
      10% of revenues, repectively, for the quarter ended June 30, 2001. The
      Company had two customers accounting for 13% and 12% of revenues,
      respectively, for the six months ended June 30, 2002 and one customer that
      accounted for 27% of revenues for the six months ended June 30, 2001.

5.    Earnings Per Share

      The Company computes, presents and discloses earnings per share in
      accordance with SFAS 128 "Earnings Per Share" ("EPS") which specifies the
      computation, presentation and disclosure requirements for earnings per
      share of entities with publicly held common stock or potential common
      stock. The statement defines two earnings per share calculations, basic
      and assuming dilution. The objective of basic EPS is to measure the
      performance of an entity over the reporting period by dividing income
      available to common stock by the weighted average shares outstanding. The
      objective of diluted EPS is consistent with that of basic EPS, that is to
      measure the performance of an entity over the reporting period, while
      giving effect to all dilutive potential common shares that were
      outstanding during the period. The calculation of diluted EPS is similar
      to basic EPS except both the numerator and denominator are increased for
      the conversion of potential common shares. Due to the Company's net loss
      for the three month and six month periods ended June 30, 2002 and 2001,
      all outstanding stock options are considered to be anti-dilutive.

      At June 30, 2002, the exercise prices of all outstanding stock options
      exceeded the market price of the Company's common stock. All outstanding
      options to purchase 795,006 shares of common stock are antidilutive and
      excluded from the computation of diluted loss per share for the three and
      six month periods ended June 30, 2002.

6.    Restructuring and Other Charges

      In the first quarter of 2002, the Company decided to close its San Ramon,
      California office and reduce the sales and marketing workforce by a total
      of five employees.

      The approximate restructuring and other charges recorded in the first
      quarter 2002 are summarized as follows:

      Common stock consideration has been calculated based on Emerging Issues
      Task Force Issue ("EITF") 99-12, "Accounting for Formula Arrangements
      under EITF 95-19". For this calculation, DSET used the average market
      price for a few days before and after the merger was agreed to and
      announced, June 26, 2001 ($2.796 per common share).

      The fair value of ISPsoft's options exchanged for the Company's options
      has been calculated based on FASB Interpretation No. 44, "Accounting for
      Certain Transactions Involving Stock Compensation - an interpretation of
      APB Opinion No. 25" and EITF 00-23, "Issues Related to the Accounting for
      Stock Compensation Under APB 25 and FIN 44." DSET used the average market
      price for a few days before and after the merger was agreed to (as
      explained above) for the vested portion of the options issued, and the
      market price on the consummation date, January 31, 2002, for the unvested
      portion.

      Selected Pro Forma Financial Information

      The Company has prepared a pro forma loss statement in accordance with
      SFAS 141, for the three and six month periods ended June 30, 2002 and 2001
      as if ISPsoft were part of DSET as of January 1, 2002 and 2001,
      respectively. In the period ended January 31, 2002, ISPsoft recorded a
      non-recurring item which decreased the provision for income taxes expense
      by $227,000 for the sale of ISPsoft tax credits, which is included below
      in the selected pro forma information.

8.   Impairment of Goodwill

     In June 2002, the Company recorded a charge for the impairment of goodwill
     of $11.4 million relating to DSET's merger with ISPsoft Inc. in January
     2002. The amount of impairment reflects both the further decline in the
     Company's stock price and resulting market valuation in recent months and a
     reassessment of the market outlook for capital equipment and software
     purchases in the telecommunications industry. Under SFAS 142, a goodwill
     impairment is deemed to exist if the net book value of a reporting unit
     exceeds its estimated fair value. The fair value was determined based on
     the recent market value of the Company's shares. This charge is
     non-operational in nature and does not affect cash flows.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations.

General

     DSET develops and markets service-provisioning and electronic-bonding
solutions for use by telecommunications providers around the world. Our
IPSource'TM' software platform, acquired in our merger with ISPsoft in January
2002, enables a service provider to provision, activate, and manage services
such as Internet Protocol ("IP") based virtual private networks ("VPNs") in
complex multi-vendor network environments. We also offer a family of software
solutions for competitive service providers ("CSPs") that enables them to
exchange information with other telecommunications service providers to reduce
the time necessary to provision new voice and data services for their customers.

     1999 and 2000 were years of unprecedented demand for all types of
communications products and services. Companies in the telecommunications
industry had access to and utilized abundant sources of investment capital.
However, the downturn in the industry, which began in the second half of 2000,
reduced our revenues significantly beginning in the third quarter of 2000 and
through the second quarter of 2002. This downturn was brought about by the
sudden withdrawal of available financing from almost all of the traditional
financing sources (vendors, lenders, private equity/venture capital sources,
public equity markets and large corporate partners) to our current and potential
customers. Prior to this downturn, the new CSPs were successfully and regularly
obtaining large capital commitments allowing them to increase the size and the
pace of their infrastructure spending. This funding crisis also affected our
collection efforts since many customers either declared bankruptcy or concluded
that they did not have sufficient available cash to pay their obligations to
DSET. We believe that we have adequately reserved for doubtful accounts,
although no assurance can be made that additional customers will not go bankrupt
or have financial difficulties.

     Our policy to assess the probability of collection consists of reviewing
public and private sources of financial information for all potential customers
(e.g., financial statements, periodic filings and press releases), inquiring of
management of the potential customer how they intend to pay for their purchase,
reviewing available information from credit rating agencies, and if available,
contacting funding sources, reviewing recent announcements regarding completed
and proposed financing and discussing the potential customer's credit worthiness
with other suppliers.

     In the second half of 2000 and continuing through the second quarter of
2002, the business models of many service providers came into doubt. The
industry continues to see a dramatic decline in the availability of capital and
spending by service providers. 2001 can be characterized as a year of survival
and retrenchment for the industry, with the contraction of the CSPs severely
impacting hardware and software vendors that had previously experienced
substantial growth in revenues and profits. Virtually every company that
remained in business,


                                       19




<PAGE>


including DSET, had to reorganize. In 2001, we incurred substantial losses, and
accordingly reduced headcount and expenses in an effort to conserve cash. We
have utilized cash previously invested in marketable securities to finance the
losses brought about by the downturn. Through the second quarter of 2002, we
continue to see turmoil in the industry as additional customers have either
commenced or declared their intent to commence formal reorganization
proceedings.

     For our electronic bonding gateway products, we currently offer two
additional sales models, in addition to the traditional perpetual license and
services arrangement, to our customers to acquire our products and services: a
transaction based payment plan ("Pay as You Grow") and a rental program with
little cash due up front ("Gateway Rental Program"). Prior to the inclusion of
these alternative programs, our license revenues were derived from the sale of
electronic-bonding gateways to CSPs under contracts that provided for perpetual
licenses and corresponding fees, with the total price of a license sale to a
customer depending on the number of licensed products, the number of trading
partners and amount of additional services acquired.

     In the fourth quarter of 2001, in an effort to find the right financial
model to encourage CSPs to once again start buying electronic-bonding gateways,
we announced our Gateway Rental Program, which provides existing and prospective
customers the ability to rent electronic-bonding gateways on a month-to-month
basis, with a 90-day cancellation provision. The program includes the use of the
software, technical support, software upgrades and change management services
for a monthly charge that is roughly equivalent to what they had been paying for
the maintenance services only. Service revenue is recognized in the month in
which customers use our software and services.

     Prospective customers for our IPSource'TM' products are offered the basic
platform under a perpetual license and the right to establish services on a
usage basis similar to the "pay as you grow" model for gateways. This allows
prospective customers to only pay for those services or device drivers that they
need to provision and activate their customers' services.

     Presently, we are in the process of conducting a trial of the IPSource'TM'
software with a major network provider and plan to initiate trials with
additional prospective customers in the near future. These trials are generally
required by prospects prior to purchasing software similar to IPSource'TM'.

     Our service revenues are comprised of fees derived from custom program
development, implementation, installation, training fees and maintenance. Our
custom program development services are generally individually negotiated and
contracted for on a fixed price basis. Prices for such projects vary depending
upon the size and scope of the project and estimated time and effort to
completion. Revenues from custom program development services are generally
recognized on a percentage of completion basis calculated as direct labor costs
are incurred in relation to estimated total direct labor costs at completion for
each project. The impact of revisions in percentage of completion estimates is
reflected in the period in which the revisions are made. Maintenance services,
for which we typically charge annually between 15% and 30% of the price


                                       20




<PAGE>



of the products licensed by the customer annually, may be purchased at the
customer's option. Maintenance fees are recognized as service revenue over the
term of the maintenance period.

     Our cost of license revenues consists primarily of royalties paid to
third-party software companies and the amortization of acquired technology and
capitalized software development costs. We generally are not contractually
obligated to make minimum royalty payments. Costs of service revenues include,
primarily, payroll, related benefit costs, personnel and other operating
expenses. Sales and marketing expenses consist of salaries, commissions and
bonuses paid to sales and marketing personnel, as well as travel and promotional
expenses. Research and product development expenses encompass primarily software
engineering personnel costs, costs of third-party equipment, costs associated
with customer satisfaction and quality and software utilized for development
purposes. Research and product development expenses are charged to operations as
such costs are incurred. Our research and development projects are evaluated for
technological feasibility in order to determine whether they meet capitalization
requirements. General and administrative expenses are comprised of personnel
costs and occupancy costs for administrative, executive and finance personnel.

     For the quarters ended June 30, 2002 and 2001, we derived approximately
10.3% and 22.4%, respectively, of our total revenues from license revenues and
approximately 89.7% and 77.6%, respectively, of our total revenues from service
revenues. During the second quarter of 2002, revenues generated from CSPs were
approximately $1.1 million and revenues generated from network equipment vendors
for LNP solutions, application development tools and related services were
approximately $146,000. During the second quarter of 2001, revenues generated
from CSPs were $2.0 million and revenues generated from network equipment
vendors were approximately $600,000.

     We had two customers accounting for 12% revenues each, for the quarter
ended June 30, 2002 and two customers that accounted for 14% and 10% of
revenues, respectively, for the quarter ended June 30, 2001. Revenues from
international sales are currently insignificant.

     The merger with ISPsoft was completed on January 31, 2002. ISPsoft has
developed what we believe to be a technically advanced version of IP
provisioning software. The global market for next generation IP based
service activation and configuration management solutions is expected to grow
from approximately $800 million in 2001 to almost $1.4 billion in 2005,
according to data compiled by the Yankee Group. At closing, ISPsoft security
holders received an aggregate of 2,281,143 shares of DSET common stock,
$1,000,000 in cash, issuance of an aggregate of $800,000 of DSET promissory
notes payable and payment of $544,519 in cash in exchange for certain debts
payable by ISPsoft to certain ISPsoft security holders and/or affiliates and
were entitled to receive up to $500,000 in cash and/or unregistered shares of
DSET common stock in potential milestone payments (if revenues from ISPsoft
products were $4.0 million by June 30, 2002) in exchange for their ISPsoft
securities in the merger. The milestone payments were not required. In addition,
we loaned ISPsoft $4.4 million through the consummation of the transaction. We
also assumed the ISPsoft 2000 Stock Plan and granted the holders of 2,781,010
issued and


                                       21




<PAGE>


outstanding options to purchase shares of ISPsoft common stock the right to
purchase up to 241,483 shares of DSET common stock.

     In June 2002, the Company recorded a charge for the impairment of goodwill
of $11.4 million relating to DSET's merger with ISPsoft Inc. in January 2002.
The amount of impairment reflects both the further decline in the Company's
stock price and resulting market valuation in recent months and a reassessment
of the market outlook for capital equipment and software purchases in the
telecommunications industry. Under SFAS 142, a goodwill impairment is deemed to
exist if the net book value of a reporting unit exceeds its estimated fair
value. The fair value was determined based on the recent market value of the
Company's shares. This charge is non-operational in nature and does not affect
cash flows.

     Forward-Looking Statements

     Statements contained in this Form 10-Q that are not based on historical
fact are "forward-looking statements" within the meaning of Section 21E of the
Securities Exchange Act of 1934, as amended. Forward-looking statements may be
identified by the use of forward-looking terminology such as "may," "will,"
"should," "expect," "estimate," "anticipate," "continue," or similar terms,
variations of such terms or the negative of those terms. Such forward-looking
statements involve risks and uncertainties, including, but not limited to: (i)
our ability to continue as a going concern; (ii) risks associated with the
integration of ISPsoft with us following our recent acquisition of ISPsoft and
the potential acquisition of other businesses by us, including risks relating to
unanticipated liabilities or expenses, lower than expected revenues and the
commercialization of acquired technology or products; (iii) the need for
substantial financing to continue operations; (iv) the risk that our common
stock may be delisted from the Nasdaq SmallCap Market; (v) our dependence on the
market for advanced telecommunications products and services; (vi) rapid
technological change in our industry; (vii) our lack of an operating history in
providing Internet Protocol (IP) based provisioning and management applications
and services; (viii) the failure to protect proprietary rights or enforce
licensing rights; and (ix) the loss of third-party software we utilize in our
products. The success of the Company depends to a large degree upon increased
demand by telecom service providers for our products and services, and the
market for IP provisioning software. As a result of such risks and others
expressed from time to time in our filings with the Securities and Exchange
Commission, our actual results may differ materially from the results discussed
in or implied by the forward-looking statements contained herein.

     Critical Accounting Estimates and Judgments

         Our discussion and analysis of our financial condition and results of
operations are based upon our condensed consolidated financial statements, which
have been prepared in accordance with accounting principles generally accepted
in the United States of America. The preparation of these financial statements
requires us to make estimates and judgments that affect the reported amounts of
assets, liabilities, revenues and expenses, and related disclosure of contingent
assets


                                       22




<PAGE>



and liabilities. On an on-going basis, we evaluate our estimates, including
those related to bad debts, investments, recoverability of long-lived assets,
income taxes, restructuring charges, post-contract customer support agreements,
and contingencies and litigation. We base our estimates on historical experience
and on various other assumptions that we believe to be reasonable under the
circumstances, the results of which form the basis for making judgments about
the carrying values of assets and liabilities that are not readily apparent from
other sources. Actual results may differ from these estimates under different
assumptions or conditions.

As more fully described in Note 3 to our consolidated financial statements, we
believe the following critical accounting policies affect our more significant
judgments and estimates used in the preparation of our consolidated financial
statements.

     o  We recognize both product and service revenue.

         o  We do not recognize revenue if, in our judgment, the revenue does
            not meet the requirements of AICPA Statement of Position ("SOP")
            97-2, `Software Revenue Recognition' (i.e., persuasive evidence that
            an arrangement exists, delivery has occurred, the customer's fee is
            fixed and determinable and collectibility is probable).

         o  On long-term, fixed price contracts, we recognize revenue using the
            percentage-of-completion method in accordance with SOP 81-1,
            "Accounting for Performance of Construction-Type and Certain
            Production-Type Contracts." As work progresses, we rely on estimates
            of total expected contract revenue and costs. We follow this method
            since reasonably dependable estimates of the revenue and costs
            applicable to various stages of a contract can be made. Recognized
            revenues and profit are subject to revisions as the contract
            progresses to completion. Revisions in profit estimates are credited
            to income in the period in which the facts that give rise to the
            revision become known.

     o  We maintain allowances for doubtful accounts for estimated losses
        resulting from the inability of our customers to make required payments.
        If the financial condition of our customers deteriorates, resulting in
        an impairment of their ability to make payments, additional allowances
        may be required.

     o  We make a determination as to the carrying value of intangibles,
        long-lived assets such as acquired technology and related goodwill that
        may not be recoverable based upon the existence of indicators of
        impairment and measure any impairment in accordance with the provisions
        of SFAS 142 and SFAS 144, based on applying the appropriate fair value
        methodology.

     o  Contraction of the telecommunications industry commencing in the latter
        half of 2000 and continuing through the second quarter of 2002 has led
        us to re-examine all facets of


                                       23




<PAGE>


        our business. In the face of declining revenues and certain customers'
        unwillingness or inability to honor their commitments, it became
        necessary for us to take steps to reorganize to a level commensurate
        with the expected reduced revenue levels. These steps included
        recognizing asset impairments on many of our long-lived intangible and
        tangible assets, closing facilities, reducing and consolidating the
        workforce, seeking sublet tenants for portions of facilities covered by
        long term operating leases, and recognizing charges against earnings in
        the current period for future fixed asset and facility lease payments
        that will not benefit future periods. Considerable management judgment
        is necessary to estimate the charges for asset impairments and
        restructuring. Restructuring charges derived from our plans of closing
        facilities and discontinuing certain product lines are recognized
        pursuant to Emerging Issues Task Force ("EITF") No. 94-3, "Liability
        Recognition for Certain Employee Termination Benefits and Other Costs to
        Exit an Activity (Including Certain Costs Incurred in a Restructuring)"
        and Staff Accounting Bulletin ("SAB") 100, "Restructuring and Impairment
        Charges".

     o  We record a valuation allowance to reduce our deferred tax assets to the
        amount that is more likely than not to be realized. While we have
        considered future taxable income and ongoing prudent and feasible tax
        planning strategies in assessing the need for the valuation allowance,
        in the event we were to determine that we would be able to realize our
        deferred tax assets in the future in excess of our net recorded amount
        (zero at June 30, 2002 and December 31, 2001), an adjustment to the
        deferred tax asset would increase income in the period such
        determination was made.

     o  The financial statements have been prepared on the basis that we will
        continue as a going concern, which contemplates the realization of
        assets and satisfaction of liabilities and commitments in the normal
        course of business. The consolidated financial statements do not include
        any adjustments relating to the recoverability of the carrying amount of
        the recorded assets and liabilities that might result from the outcome
        of this uncertainty.

     Results of Operations

     Three Months Ended June 30, 2002 Compared to the Three Months Ended
     June 30, 2001

         Revenues. Total revenues decreased by 54.1% to $1.2 million in the
     second quarter of 2002 from $2.6 million in the second quarter of 2001.
     License revenues decreased by 78.9% to $123,500 in the second quarter of
     2002 from $586,000 in the second quarter of 2001. This decrease was
     attributable to the downturn in the telecom industry, especially in our
     market niche, resulting in a reduction in orders by prospective customers
     due to poor operating results of the CSPs, and the absence of available
     funding from capital markets to these prospective customers. Service
     revenues decreased 46.9% to $1.1 million in the second quarter of 2002 from
     $2.0 million in the second quarter of 2001. This decrease reflects a
     $500,000 decrease in gateway solutions service revenue, a $400,000 decrease
     in revenue for network solutions and a $92,000 decrease in LNP solutions
     revenue.


                                       24




<PAGE>


          Gross profit. The Company's gross profit decreased 64.5% to $187,400
     in the second quarter of 2002 from $527,200 in the second quarter of 2001.
     Gross profit (loss) percentage for license revenues decreased to (7.9%) in
     the second quarter of 2002 from 10.6% in the second quarter of 2001. Gross
     profit percentage for service revenues decreased to 18.3% in the second
     quarter of 2002 from 22.9% in the second quarter of 2001. The decrease is
     primarily due to the amortization of acquired technology in the amount of
     $200,000 for the current quarter.

         Sales and marketing expenses. Sales and marketing expenses decreased
     76.6% to $495,000 in the second quarter of 2002 from $2.1 million in the
     second quarter of 2001. The decrease in sales and marketing expenses
     reflects a $1.0 million decrease in personnel related expenses, a $300,000
     decrease in occupancy costs and depreciation, a $200,000 decrease in
     travel, and a $100,000 decrease in commissions (due to reduced sales). The
     decrease was mainly due to a drop in average headcount in applicable
     departments to eleven in the second quarter of 2002 as compared to 37 for
     the second quarter of 2001.

         Research and product development expenses. Research and product
     development expenses decreased 63.5% to $1.1 million in the second quarter
     of 2002 from $3.0 million in the second quarter of 2001. Personnel related
     expenses decreased by $1.3 million, depreciation and occupancy and related
     costs decreased by $400,000, travel and telephone expense decreased by
     $100,000, and other expenses decreased by a net amount of $100,000. The
     decrease was mainly due to a drop in average headcount in this department
     to 27 in the second quarter of 2002 as compared to 69 for the second
     quarter of 2001.

         General and administrative expenses. General and administrative
     expenses decreased 35.6% to $900,000 in the second quarter of 2002 from
     $1.4 million in the second quarter of 2001. The decrease in general and
     administrative expenses was mainly due to a decrease of $200,000 in
     occupancy and depreciation costs, a $100,000 decrease in personnel and
     related expenses, a $100,000 decrease in recruiting expenses and a $100,000
     decrease in miscellaneous other expenses.

         Bad debt expense. Bad debt expense was a credit of $307,000 in the
     second quarter of 2002, due to the collection of previously reserved
     accounts. Bad debt expense was $545,000 in the second quarter of 2001. The
     Company's bad debt expense recorded in the second quarter of 2001
     corresponded to $307,000 of revenue recognized in 1999, $218,000 of revenue
     recognized in 2000, and $20,000 of revenue recognized in the first quarter
     of 2001.

         Amortization of goodwill and other intangibles. Amortization expense
     was zero in the second quarter of 2002 compared to $103,000 in the second
     quarter of 2001. The reduction is due to the effect of SFAS 142, which was
     adopted on January 1, 2002 whereby goodwill amortization ceased.

         Restructuring and other charges. Restructuring and other charges in the
     second quarter of 2002 were $1.8 million which included a severance charge
     of $948,900 for the reorganization of all departments within the Company,
     $628,400 for the impairment of fixed assets


                                       25




<PAGE>


     including leasehold improvements associated with the closed Bridgewater
     facility, a $177,100 increase to the officer's loan reserve based on the
     severance agreement of the former CEO, and $32,000 for legal, moving, and
     rent charges associated with the closure of the Bridgewater, New Jersey
     office. In the second quarter of 2001, a $6.4 million charge was taken
     which included an asset impairment of $4.1 million for the carrying value
     of certain licenses related to acquired technology, approximately $1.0
     million in charges related to severances in June 2001 and $1.3 million in
     charges related to fixed asset impairments and non-refundable future lease
     payments.

     Impairment of goodwill. In the second quarter of 2002, a charge was taken
     for the impairment of goodwill of $11.4 million relating to DSET's merger
     with ISPsoft Inc. in January 2002. The amount of impairment reflects both
     the further decline in the Company's stock price and resulting market
     valuation in recent months and a reassessment of the market outlook for
     capital equipment and software purchases in the telecommunications
     industry. Under SFAS 142, a goodwill impairment is deemed to exist if the
     net book value of a reporting unit exceeds its estimated fair value. The
     fair value was determined based on the recent market value of the Company's
     shares. In the second quarter of 2001, a $420,000 charge was taken for the
     impairment of goodwill related to DSET's electronic-bonding gateway
     business.

         Interest expense and other income (expense). Interest expense and other
     income and expense decreased to an expense of $13,000 for the second
     quarter of 2002 from an expense of $31,000 for the second quarter of 2001.
     The difference was due to the accrual of interest expense on a note
     payable, which was paid in full in March 2002.

         Interest income and realized gains and losses on marketable securities.
     Interest income decreased to $20,000 in the second quarter of 2002 as
     compared to approximately $404,000 in the second quarter of 2001. This
     decrease was due to lower principal balances in 2002 due to the funding of
     operations and reduced interest rates due to the current economic climate
     as well as lower realized gains from redemptions of marketable securities
     and interest received on federal income tax refunds.

         Income taxes. A tax benefit of $449,000 was recognized for the second
     quarter of 2002 as compared to a tax provision (expense) of $98,000 in the
     second quarter of 2001. The tax benefit in the second quarter of 2002
     relates to the Job Creation and Worker Assistance Act ("JCWAA") signed into
     law in March 2002, which allows an extension to the general net operating
     loss carry-back period to five years (from two years). The benefit in the
     second quarter of 2002 related to the research and development tax credit
     and the foreign tax credit released as a result of the carry-back related
     to the JCWAA. The benefit was recorded in the second quarter as a result of
     further clarification of the legislation. The 2002 and 2001 rates differ
     substantially from the statutory rate due to our losses and the effects of
     the JCWAA.

     Six Months Ended June 30, 2002 Compared to the Six Months Ended June
     30, 2001

         Revenues. Total revenues decreased by 55.2% to $2.7 million in the six
     months ended June 30, 2002 from $6.0 million in the six months ended June
     30, 2001. License revenues decreased by 82.1% to $377,000 in the six months
     ended June 30, 2002 from $2.1 million in the six months ended June 30,
     2001. This decrease reflects a downturn in the telecom industry, especially
     in our market niche, resulting in a reduction in orders by prospective
     customers due to poor operating results of the CSPs, and the absence of
     available funding from capital markets to these prospective customers.
     Service revenues decreased 40.7% to $2.3 million in the six months ended
     June 30, 2002 from $3.9 million in the six months ended June 30, 2001. This
     decrease was attributable to a $900,000 decrease in revenue for network
     solutions, a $600,000 decrease in gateway solutions service revenue and a
     $92,000 decrease in LNP solutions revenue.

          Gross profit. The Company's gross profit decreased 68.8% to $451,900
     in the six months ended June 30, 2002 from $1,450,000 in the six months
     ended June 30, 2001. Gross profit percentage for license revenues decreased
     to 10.9% in the six months ended June 30, 2002 from 51.3% in the six months
     ended June 30, 2001. The decrease was due to one large contract signed in
     the six months ended June 30, 2001, for which there was a significant gross
     profit. Gross profit percentage for service revenues decreased to 17.7% in
     the six months ended June 30, 2002 from 9.4% in the six months ended June
     30, 2001. The difference is mainly due to the amortization of acquired
     technology of $333,333 during the six months ending June 30, 2002.

         Sales and marketing expenses. Sales and marketing expenses decreased
     73.5% to $1.2 million in the six months ended June 30, 2002 from $4.6
     million in the six months ended June 30, 2001. The decrease in sales and
     marketing expenses reflects a $2.2 million decrease in personnel related
     expenses, a $600,000 decrease in occupancy costs and depreciation, a
     $400,000 decrease in travel expenses and a $200,000 decrease in
     commissions. The decrease was mainly due to a drop in average headcount for
     these departments.

         Research and product development expenses. Research and product
     development expenses decreased 69.9% to $2.1 million in the six months
     ended June 30, 2002 from $6.9 million in the six months ended June 30,
     2001. Personnel related expenses decreased by $3.4 million, depreciation
     and occupancy and related costs decreased by $800,000, contract labor
     decreased by $300,000, travel and telephone expense decreased by $200,000,
     and hardware and software maintenance decreased by $100,000. The decrease
     was mainly due to a 70% decrease in average headcount for this department;
     27 employees as compared to 90 employees.

         General and administrative expenses. General and administrative
     expenses decreased 34.8% to $2.1 million in the six months ended June 30,
     2002 from $3.3 million in the six months ended June 30, 2001. The decrease
     in general and administrative expenses reflects a decrease of $300,000 in
     occupancy and depreciation costs, a $200,000 decrease in personnel related
     expenses, a $200,000 decrease in recruiting expense, a $200,000 decrease in


                                       27




<PAGE>



     relocation expenses, a $100,000 decrease in contract labor costs, a
     $100,000 decrease in legal and accounting expenses, and a $100,000 decrease
     in miscellaneous other expenses.

         Bad debt expense. Bad debt expense was a credit of $307,000 in the six
     months ended June 30, 2002 due to the collection of previously reserved
     accounts. Bad debt expense was $985,000 in the six months ended June 30,
     2001. The Company's bad debt expense recorded for the six months ended June
     30, 2001 corresponded to $609,000 of revenue recognized in 1999, $356,000
     of revenue recognized in 2000, and $20,000 of revenue recognized in the
     first quarter of 2001.

         Amortization of goodwill and other intangibles. Amortization expense
     was zero in the six months ended June 30, 2002 compared to $200,000 in the
     six months ended June 30, 2001. The reduction is due to the effect of SFAS
     142, which was adopted on January 1, 2002 whereby goodwill amortization
     ceased.

              Restructuring and other charges. Restructuring and other charges
     in the six months ended June 30, 2002 were $2,250,000 which included a
     severance charge of $1,234,000 for the reorganization in the sales and
     marketing departments, $775,000 for the impairment of fixed assets, a
     $177,000 addition to the officer's loan reserve, and $64,000 for legal,
     moving, and rent charges associated with the closing of the offices in San
     Ramon, California and Bridgewater, New Jersey. In the six months ended June
     30, 2001, a $9.8 million dollar charge was taken, which included asset
     impairments of $6.3 million for the carrying value of certain licenses
     related to acquired technology, $1.3 million in severance charges related
     to the March and June staffing reductions and $2.2 million for fixed asset
     impairment and non-refundable future lease payments.

         Impairment of goodwill. Charges for the impairment of goodwill in the
     six months ended June 30, 2002 of $11.4 million were related to DSET's
     merger with ISPsoft Inc. in January 2002. The amount of impairment reflects
     both the further decline in the Company's stock price and resulting market
     valuation in recent months and a reassessment of the market outlook for
     capital equipment and software purchases in the telecommunications
     industry. Under SFAS 142, a goodwill impairment is deemed to exist if the
     net book value of a reporting unit exceeds its estimated fair value. The
     fair value was determined based on the recent market value of the Company's
     shares.

         In the six month period ended June 30, 2001 charges for the impairment
     of goodwill were $420,000 related to DSET's electronic-bonding gateway
     business.

         Interest expense and other income (expense). Interest expense and other
     income and expense decreased to $77,000 for the six months ended June 30,
     2002 from an expense of $78,000 for the six months ended June 30, 2001.

         Interest income and realized gains and losses on marketable securities.
     Interest income decreased to $66,000 in the six months ended June 30, 2002
     as compared to approximately $894,000 in the six months ended June 30,
     2001. This decrease was due to lower principal balances in 2002 due to the
     funding of operations and reduced interest rates due to the current


                                       28




<PAGE>


     economic climate as well as lower realized gains from redemptions of
     marketable securities and interest received on federal income tax refunds.

         Income taxes. We recognized a tax benefit of $1.8 million for the six
     months ended June 30, 2002 as compared to a tax provision of $127,000 in
     the six months ended June 30, 2001. The tax benefit in 2002 relates to the
     Job Creation and Worker Assistance Act ("JCWAA") signed into law in March
     2002, which allows an extension to the general net operating loss
     carry-back period to five years (from two years). The 2002 and 2001 rates
     differ substantially from the statutory rate due to our losses.

Liquidity and Capital Resources

         Our condensed consolidated financial statements have been prepared on
     the basis that we will continue as a going concern, which contemplates the
     realization of assets and satisfaction of liabilities and commitments in
     the normal course of business. At June 30, 2002, our cash and cash
     equivalents aggregated approximately $3.9 million. At December 31, 2001 our
     cash and cash equivalents totaled $13.0 million. Our working capital
     (deficit) was ($200,000) and $8.5 million at June 30, 2002 and December 31,
     2001, respectively.

         At June 30, 2002, our principal sources of liquidity were our cash and
     cash equivalents that totaled $3.9 million. In addition, we expect to
     receive $449,000 in cash for the expected U.S. Federal Income Tax refund
     due to the amended tax return to claim the research and development tax
     credit and foreign tax credit which is released as a result of an NOL
     carry-back from 2001 to 1996 which released the 1996 research and
     development tax credit and the foreign tax credit due to the new tax
     carry-back provisions of the JCWAA. This refund should be received in the
     fourth quarter of 2002.

           Our operating activities used cash of $4.9 million and $11.5 million
     for the six months ended June 30, 2002 and 2001, respectively. Cash used by
     operations in the six months ended June 30, 2002 was primarily attributable
     to a net loss adjusted for the non-cash charges for impairment of goodwill,
     amortization, depreciation and restructuring, as well as an increase in
     income taxes receivable, offset by decreases in deferred revenues, deferred
     rent, accounts payable and accrued expenses.

         Cash provided by (used in) investing activities in the six months ended
     June 30, 2002, and 2001 was ($3.7) million and $10.6 million, respectively.
     Cash used in investing activities in the six months ended June 30, 2002 was
     primarily attributable to the merger with ISPsoft Inc. We expect minimal
     capital equipment and leasehold improvement expenditures to be made in
     2002.

         We used approximately $483,000 and $556,000 in cash in financing
     activities in the six months ended June 30, 2002, and 2001, respectively,
     relating mainly to the repayment of loans.

         In addition, in 2002 DSET has received three non-compliance
     notifications from the Nasdaq Stock Market, Inc. ("Nasdaq").


                                       29




<PAGE>



         On February 14, 2002, we received notice from the Nasdaq Stock Market,
     Inc. ("Nasdaq") that for the preceding 30 consecutive trading days, our
     common stock had not maintained the minimum Market Value of Publicly Held
     Shares ("MVPHS") of $5,000,000 as required for continued inclusion by
     Marketplace Rule 4450(a)(2) on the Nasdaq National Market. MVPHS equals the
     closing bid price multiplied by that portion of a company's outstanding
     shares which is in the hands of public investors (i.e., - shares not held
     by company officers, directors, or investors who hold a controlling
     interest in the company.) Therefore, in accordance with Marketplace Rule
     4450(e)(1), we had 90 calendar days, or until May 15, 2002, to regain
     compliance. Effective May 29, 2002, the Company transferred the trading of
     its common stock to the Nasdaq SmallCap Market and no further action was
     taken by Nasdaq.

      On March 5, 2002, we received notice from Nasdaq that for the previous 30
     consecutive trading days, the price of our common stock had closed below
     the minimum $1.00 per share requirement for continued inclusion under
     Marketplace Rule 4450(a)(5). Therefore, in accordance with Marketplace Rule
     4450(e)(2), we had 90 calendar days, or until June 3, 2002, to regain
     compliance. If compliance with this Rule could not be demonstrated by
     June 3, 2002, our securities would have been delisted from the Nasdaq
     National Market. Effective May 29, 2002 the Company transferred the trading
     of its common stock to the Nasdaq SmallCap Market.

     On July 17, 2002, the Company received notice from Nasdaq that for the
     previous 30 consecutive trading days, the price of the Company's common
     stock has not maintained a minimum market value of publicly held shares of
     $1,000,000 as required for continued inclusion by Marketplace Rule
     4310(c)(7). Therefore, in accordance with Marketplace Rule 4310(c)(8)(B),
     the Company has 90 calendar days, or until October 15, 2002, to regain
     compliance. If compliance with the $1,000,000 Rule cannot be demonstrated
     by October 15, 2002, the Company will receive a written notification from
     the Nasdaq that the Company's securities will be delisted.

     Our failure to meet the Nasdaq's maintenance criteria in the future may
     result in the delisting of our common stock from the Nasdaq SmallCap
     Market. In such event, trading, if any, of DSET's common stock may then
     continue to be conducted in the over-the-counter market, on the
     over-the-counter bulletin board or other electronic quotation services. As
     a result, an investor may find it more difficult to dispose of or obtain
     accurate quotations as to the market value of DSET's common stock. In
     addition, in the event DSET's common stock is delisted, broker-dealers
     would have certain regulatory burdens imposed upon them, which may
     discourage them from effecting transactions in DSET's common stock, further
     limiting the liquidity thereof. This may have the effect of limiting our
     ability to raise additional financing.

     Our ability to continue as a going concern is dependent upon our ability
     to generate sufficient cash flows to meet our obligations as they come
     due. We believe that the cost reductions from our restructurings in 2001
     and the first half of 2002 (including work force


                                       30




<PAGE>


     reductions) and the merger with ISPsoft will enhance our cash flows from
     operations. We are seeking additional financing to fund our operating and
     capital requirements through 2002. If cashflows are insufficient or we are
     unable to raise funds on acceptable terms, there would be a material
     adverse effect on our financial position and operations and our ability to
     continue as a going concern. This would force us to further reduce our
     capital expenditures, reduce our work force, sell certain assets, or
     possibly explore other alternatives including seeking bankruptcy
     protection. The consolidated financial statements do not include any
     adjustments relating to the recoverability of the carrying amount of the
     recorded assets or the amount of liabilities that might result from the
     outcome of these uncertainties. We cannot be certain that additional debt
     or equity financing will be available when required or, if available, that
     we can secure it on terms satisfactory to us.

     Accounts receivable, net, decreased to $774,000 at June 30, 2002 from
     $824,000 at December 31, 2001, primarily as a result of decreased sales
     and the collection of outstanding receivables. Included in accounts
     receivable at June 30, 2002 was $7.4 million for trade receivables and
     $800,000 for unbilled project revenue as compared to $7.4 million for
     trade receivables and $1.1 million for unbilled project revenue at
     December 31, 2001. The allowance for doubtful accounts was $7.4 million
     and $7.7 million at June 30, 2002 and December 31, 2001, respectively.
     Unbilled project revenue is the excess amount of revenue recognized
     through percentage of completion that has not been billed to the customer.
     Payment terms to customers are generally net zero to net ninety days.

     Contractual obligations including interest on these obligations are as
     follows:

*    A total of $1.5 million is included in accrued restructuring expenses in
     the condensed consolidated financial statements for the period as of June
     30, 2002.

         We may seek additional funding through collaborative arrangements,
     borrowing money and by the sale of additional equity securities. Any sales
     of additional equity securities are likely to result in further dilution to
     our then existing shareholders. Further, if we issue additional equity
     securities, the new equity securities may have rights, preferences or
     privileges senior to those of existing holders of DSET's common stock.
     Alternatively, we may borrow money from conventional lenders, possibly at
     high interest rates, which may affect the value of our shareholders'
     holdings. Despite our efforts, funding may not be available at all or only
     on terms that are unacceptable. We also could be required to seek funds
     through arrangements with collaborative partners or others that may require
     us to relinquish rights to certain of our technologies, product candidates
     or products which we would otherwise pursue on our own.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

         We believe that we are not subject to a material impact to our
     financial position or results of operations relating to market risk
     associated with foreign currency rates or derivative securities.
